To ally whom it 'ma/y concern:

Be it known that I, FREDERICK EBERT, of VSaxon- .perspective view.

In this invention the penetrating point of the instrument is formed of two opening and closing teeth, op` erated bya central rod, with a tripping andlockinglever of peculiar construction and operation. Y

When tlie.teeth are-cl0sed, they form a Eutting- Y point; when opened they operate as lifting-arms, which hold and lraise the hay.

`In the drawings, A isa bent rod, having a brace, a, across its upper end, so as t0 form an eye, a2, by which to raise and lower the instrument, and having the two teeth B B articulated to itsjlower extremities.

Gis a central rod, articulated, at its lower end, to

lugs c c, at the inner upper edges of the teeth B B', as-

seen Ain 'the drawing, so that by raising the rod it opens the teeth, as seen in the drawing, while, by depressing it, the teeth are shilt together, s0 as to make a single penetrating point. A v

The upper end of the central rod is connected to a sliding block, or plate, D, which travels up and down on the side-rods A A as guides.

E is a link, articulated to the cross-tie, or brace, u,

or a lug, al, thereon, and forming a swinging fulcrum, to support a curved lever, F, the lower end of which, below the fulorum e, is articulated to the upper end of rod C, or a link or lug connected therewith.

\By raising the end of lever, F, the rod C and link E are brought into line with-each other, so as ,to lock the arms B B firmly in position, and hold the hay securely whileit is being elevated. p

When the hay has reached the desired elevation, a pull upon the' cord H brings down the end of lever F, raising rod G, and allowing the arms B B to close together and drop the hay. In that condition the instrument is again lowered and thrust into 'thehay, after which the end of lever F is again raised,'expand ing the arms B B', and locking them in the position shown in the drawings, as before.

Having. thus described my invention,

What I claim as new, and desire to secure by Let ters Patent, is-

The arrangement shown and described of the sliding block or plate D, and cross-tie or brace a, and lug a, with relation to the bent vrod A, link E, lever F, sliding rod C, and articulated `arms B B', as and for the purpose specified. 1

To the above specification of my invention, I have signed my hand, this'2d day lof March, 1869. FREDERICK EBERT.
